  • the lock housing is regularly mounted on the body side, so it is found on an associated Kraft Vietnamesekarosserle.
  • the locking bolt is connected to a hood, so that usually a hood lock or bonnet lock is considered. In principle, however, the procedure can also be reversed. Then the Schlie ⁇ bolzen body is connected to the body or motor vehicle, whereas the lock housing and with him the motor vehicle lock undergoes attachment to the hood or generally on the door side.

  • a gap generally remains between the door or flap and the adjacent body.
  • Such a gap should be as low as possible, especially in hoods, which are seen in the usual direction forward to avoid adverse air turbulence in the front area and concomitant air resistance during a ride.

  • the German prior application DE 10 2013 109 051 deals with a minimization of such gaps in doors or flaps.
  • the lock known therefrom is movable and in particular pivotally mounted. Following a rusting of the locking mechanism, the lock is generally moved or pivoted by a drive in such a way that a gap between the door or flap and body is minimized.
  • the drive provided for this purpose comprises an electric motor and a pivotable lever, which is called a rocker.
  • the main goal of the development is to position movable body components and in particular the vehicle hood directly above the attachments, such as a headlight, a grille or the body.
  • the vehicle hood should be positioned on or immediately above the other attachments, so that an O-joint is achieved.
  • Such joints between attachments and / or the body and the hood on the one hand, as described, affect the aerodynamics of the motor vehicle and on the other hand crucially affect the visual and thus the overall qualitative impression of the vehicle.
  • a technical problem to be solved in this case is that when the motor vehicle hood is closed, primarily due to the weight, the hood performs an upper stroke.
  • An overstroke here is the exceeding of the target position of the closed hood, wherein the hood moves above the target position out, so that a 0-joint with conventional locks can not be realized.
  • a closing device for a door or flap has a lock with a catch of rotary latch and pawl for rusting the catch on.
  • the lock comprises a closing aid so as to reduce an aforementioned gap by partially moving the locking mechanism.
  • a lock with closing aid comprises a rotary latch which can be locked in both a pre-locking position and in a main locking position by at least one pawl. If the catch is locked by a pawl, so is a blocking surface of the pawl directly against a locking surface of the catch. As a result, the catch is locked reliably so that this locking mechanism will not open even with larger external load.
  • the lock with a closing aid on a locking mechanism which prevents the locking mechanism can be moved manually from the pre-locking position to the main locking position.
  • a stop for the striker can be provided, which prevents the striker can be moved so far by closing a door or flap in the inlet mouth of a catch that the catch can be locked in the main latching position. If the locking mechanism is locked by a pawl in the pre-locking position, this position is registered by pressing a microswitch, for example. If a microswitch registers the pre-locking position, then the microswitch is actuated. The actuation of the microswitch then sets a electric drive in progress. The drive moves the stopper out of its stop position. Thereafter, the catch is rotated in the direction of the main latching position by an electric drive until the catch is locked in the main latching position.
  • This embodiment is thus generally based on the consideration to provide a lock for minimizing the gap, which can be locked by at least one pawl in a pre-locking position and in a main latching position.
  • a tightening aid to rust off the ratchet in its primary ratchet position from the pre-rest position.
  • there is a locking mechanism that causes the lock to be locked only by the electric drive in the main latching position.
  • This embodiment ensures that the rotary latch can not be rotated to the main detent position at excessively high speed. This avoids the achievement of an excessively large overstroke. Compared to conventional locks with pre-locking position and main detent position, therefore, a gap between a flap or a door and a body can be minimized because it can be designed so that only a very small upper stroke is possible. It is thus possible in particular to reduce the gap to 4 mm and less. It is even possible to achieve a gap of 3 mm and less.
  • a stop for the rotary latch is attached to a plate in an advantageous embodiment.
  • this plate is preferably made of metal and is in particular on the body or on a door or flap of a motor vehicle attached. The plate may also be part of the bodywork of a motor vehicle.
  • the load caused by said impact is introduced by the rotary latch via the stop in the plate.
  • the locking bolt rotates the rotary latch in the direction of the closed position.
  • the rotary latch finally hits the stopper by its rotary motion and introduces the load connected to the impact into the stop.
  • the load introduced into the stop is then forwarded to the plate by attaching the stop to the plate. It is thus avoided damage to the drive by the impact and the associated mechanical stress. It is not necessary that the load is transmitted directly from the catch to the stop. It suffices an indirect transfer of the load into the stop inside.
  • the locking device is designed such that the catch is latched by the pawl before the load is introduced into the stop. This ensures particularly reliable that the locking mechanism can be locked as planned.
  • the catch is advantageously locked in the Vorrastpostion reasons mentioned above. The stop then prevents the catch in the main latching position can be locked.

  • a motor drive for the closing and / or opening device is provided.

  • This embodiment therefore comprises in particular a sensor or a microswitch which can be used to detect when the ratchet is in the main ratcheting position. If the sensor or microswitch registers that the ratchet is in the main latching position, the sensor or microswitch then activates the drive to reduce the remaining gap in a door or flap and minimize it as much as possible.
  • the catch has been previously moved by a closing aid from the pre-locking position to the main locking position so as to minimize a gap even by this movement alone.
